Hello juliehrdlicka-gm,
Welcome to Community! Recording home office expenses accurately in QuickBooks Online, ensures your business and professional income and expenses are aligned with the T2125 form (Statement of Business or Professional Activities), on your personal tax return.
To ensure you're on the right track with your entries, I encourage you to reach out to an accounting professional. They will be able to provide their expertise and the best course of action, to ensure a positive outcome on your books. If you don't have an accountant, we can help you locate a ProAdvisor in your local area by following this link.
If you have any other questions, feel free to reach back out. We would be happy to help!
